Lack of mental well-being in 15-year-olds: an undisclosed iceberg?

BACKGROUND: Young people suffer from psychiatric symptoms and illness, and the frequency of both may be higher than currently is recognized. The frequency with which young people consult GPs with emotional problems is not established. OBJECTIVE: The purpose of this study was to identify the number of 15-year-olds who consult their GP directly or indirectly with psychiatric symptoms or illness. METHODS: A two part survey was carried out involving (i) general practice casenote review; and (ii) questionnaires self-report. The subjects comprised all adolescents aged 15 years from 34 randomly selected general practices and a randomly selected subsample of these adolescents. The main outcome measures were a purpose-designed data collection sheet, General Health Questionnaire (GHQ-12) and a purpose-designed self-report questionnaire. RESULTS: In phase 1, the general practice casenotes of 2359 adolescents were examined. Five per cent of subjects were identified as attending the GP with mental health problems; 1% had attempted suicide during the year. In phase 2, 99 subjects returned completed self-report questionnaires. Although over a quarter (26%) were rated as GHQ-12 'cases' and approximately half reported having felt 'sad, unhappy or low' or 'anxious or worried' in the previous year, only one subject reported attending his/her GP with any of these concerns. CONCLUSIONS: Fifteen-year-olds rarely consult their GP about their emotional well-being, yet, with the GHQ-12, the self-reported rate of psychiatric morbidity was nearly seven times greater than that suggested by these same subjects' medical records. Although the majority of adolescents consult their GP throughout the course of a year, those with mental health problems, including those who attempt suicide, are indistinguishable in the frequency of their GP consultations from adolescents without mental health problems.     

Patient satisfaction with out-of-hours services; how do GP co-operatives compare with deputizing and practice-based arrangements?

BACKGROUND: Although the rapid growth in general practitioner (GP) co-operatives has met with GP satisfaction, little is known about patient satisfaction. This study compares patient satisfaction with co-operative, GP practice-based and deputizing arrangements within one geographical area 15 months after a co-operative had become established; and with telephone, primary care centre and home consultations within the co-operative. METHODS: A validated postal questionnaire survey of weighted samples of patients making contact with the co-operative, practice-based and deputizing arrangements was undertaken. RESULTS: A total of 1,823 (53.2 per cent) patients responded. There were no significant differences between organizations in terms of overall satisfaction, but patients using practice-based arrangements were significantly more satisfied with the waiting time for telephone consultations (p<0.001) and more satisfied with waiting times for home visits than deputizing patients (p=0.020). Within the co-operative, overall satisfaction, satisfaction with the doctor's manner and with the process of making contact was greater among those attending the primary care centre, and satisfaction with explanation and advice received greater than for patients receiving telephone consultations alone (p<0.01). Those receiving telephone advice reported increased information needs and help seeking during the following week (p< 0.05). CONCLUSIONS: Overall, patients were as satisfied with the co-operative as with practice-based or deputizing service arrangements, although many concerns were expressed about the quality of service provision. Differences in satisfaction were greater between forms of service delivery within the co-operative. Dissatisfaction with telephone consultations needs to be considered, together with issues relating to equity in access to out-of-hours' primary care centre consultations and the potential impact of NHS Direct.     

The impact of matching the patient's vocabulary: a randomized control trial

BACKGROUND: Research in general practice emphasizes the importance of matched models, beliefs and vocabulary in the consultation. OBJECTIVE: The present study aimed to explore the impact of matched and unmatched vocabulary on patient satisfaction with consultations. METHODS: The study took place in one inner city general practice. Patients (n=62) were randomized to either matched or unmatched vocabulary consultations when consulting for problems relating to sexual or bodily function or anatomy. Matched consultations required the doctor to use the same vocabulary as the patient. Unmatched consultations required the doctor to use medical vocabulary. Completed questionnaires were received from 60 patients. The main outcome measure was patient satisfaction (using the Medical Interview Satisfaction Scale). This assesses total satisfaction and has four subscales: distress relief; communication comfort; rapport; and compliance intent. Doctor satisfaction with the consultation was also assessed. RESULTS: The results showed that the two groups were comparable for demographic variables and doctor satisfaction. However, patients in the matched consultation group had significantly higher total satisfaction scores and higher ratings of rapport, communication comfort, distress relief and compliance intent than those in the unmatched group. CONCLUSION: The results indicate that a doctor's choice of vocabulary affects patient satisfaction immediately after a general practice consultation and that using the same vocabulary as the patient can improve patient outcomes.     

The value of joint general practitioner and rheumatologist consultations in primary care patients

OBJECTIVE: To compare the effects of regular referral by general practitioners to the Rheumatology outpatients' clinic with that of joint consultations by general practitioners (GPs) and rheumatologists, and to compare the subsequent treatment policy followed. DESIGN: Randomised. METHOD: In 1999 and 2000 all rheumatological patients who, according to the 17 participating GPs in the Maastricht region had an indication for referral, were referred to the outpatients' clinic or seen during a joint consultation where three GPs and one rheumatologist decided on a treatment policy in the presence of the patient. Agreement about diagnosis and diagnostic and therapeutic approaches between the rheumatologists and GPs was determined using questionnaires. The patient's state of health was assessed using the 'EuroQol health-related quality of life questionnaire' (EuroQol) and their satisfaction was determined by means of questionnaires. RESULTS: One hundred and sixty-six patients were included: 45 (27%) men and 121 (73%) women, with an average age of 53.7 years (SD: 14). The rheumatologists and the GPs differed in opinion on the diagnosis in 64% of the patients. Agreement on diagnosis resulted in greater agreement on the treatment policy than when there were discrepancies about the diagnosis. The rheumatologist used additional diagnostic tools and follow-up consultations at the outpatient clinic (78% and 65%) more frequently than during the joint consultation (44% and 15%). Patient satisfaction and general state of health were comparable in both groups.     

On the relationship between the efficiency and the quality of the consultation. A validity study.

OBJECTIVES: The aim of this study was to determine how the medical performance of physicians during consultations is related to doctor-patient communication and satisfaction of patients, taking into account the actual length of the consultations. In addition, we studied the validity of the 'efficiency-per-time score' as a measure of competence. METHODS: General practice trainees participated in a test situation in which they were confronted with six consultations with standardized (simulated) patients (SPs). All consultations were videotaped and evaluated by multiple observers, using national guidelines on medical content and on communication. The SPs scored satisfaction with the consultation using a satisfaction checklist. Forty GP-trainees were invited, of whom 34 participated. The main outcome measures were the number of obligatory actions undertaken by the GP-trainees, total number of actions undertaken, consultation time, efficiency-per-time score, patient satisfaction and quality of communication score, and the Pearson correlations between these measures. RESULTS: There was a negative correlation between the 'efficiency-per-time score' of the GP-trainees and the satisfaction of the SPs in five of the six consultations [Pearson r from -0.29 (P < 0.05) to -0.58 (P < 0.001)] and between the 'efficiency-per-time score' and the quality of the communication in three of the six consultations [Pearson r from -0.34 (P <.05) to -0.51 (P < 0.001)]. CONCLUSIONS: Short consultations with high technical medical efficiency seem to be related to bad communication and dissatisfied patients, thus questioning the validity of the 'efficiency-per-time score' as a measure of competence.     

Distance from practice moderates the relationship between patient management involving nurse telephone triage consulting and patient satisfaction with care

The ESTEEM trial was a randomised-controlled trial of telephone triage consultations in general practice. We conducted exploratory analyses on data from 9154 patients from 42 UK general practices who returned a questionnaire containing self-reported ratings of satisfaction with care following a request for a same-day consultation. Mode of care was identified through case notes review. There were seven main types: a GP face-to-face consultation, GP or nurse telephone triage consultation with no subsequent same day care, or a GP or nurse telephone triage consultation with a subsequent face-to-face consultation with a GP or a nurse. We investigated the contribution of mode of care to patient satisfaction and distance between the patient׳s home and the practice as a potential moderating factor. There was no overall association between patient satisfaction and distance from practice. However, patients managed by a nurse telephone consultation showed lowest levels of satisfaction, and satisfaction for this group of patients increased the further they lived from the practice. There was no association between any of the other modes of management and distance from practice.     

Does Media Use Result in More Active Communicators? Differences Between Native Dutch and Turkish-Dutch Patients in Information-Seeking Behavior and Participation During Consultations With General Practitioners

This study investigates differences between native Dutch and Turkish-Dutch patients with respect to media usage before and patient participation during medical consultations with general practitioners. In addition, the authors assessed the relation between patient participation and communication outcomes. The patients were recruited in the waiting rooms of general practitioners, and 191 patients (117 native Dutch, 74 Turkish-Dutch) completed pre- and postconsultation questionnaires. Of this sample, 120 patients (62.8%; 82 native Dutch, 38 Turkish-Dutch) agreed to have their consultations recorded to measure patient participation. Compared with Turkish-Dutch patients of similar educational levels, results showed that native Dutch patients used different media to search for information, participated to a greater extent during their consultations and were more responsive to their general practitioner. With respect to the Turkish-Dutch patients, media usage was related to increased patient participation, which was correlated with having fewer unfulfilled information needs; however, these relations were not found in the native Dutch patient sample. In conclusion, interventions that enhance participation among ethnic minority patients will better fulfill informational needs when such interventions stimulate information-seeking behavior in that group before a medical consultation.     

Evaluation of a telepsychiatry pilot project.

We assessed a telepsychiatry pilot project in which a psychiatric hospital was linked with mental health clinics in five general hospitals. Information was collected through questionnaires administered to patients, service providers and psychiatric consultants, and by interviews. The technology was considered easy to use by participating health-care professionals and patients, and the quality of the sound and picture was adequate. Survey data suggested acceptance and satisfaction on the part of patients, service providers and psychiatric consultants. An economic analysis indicated that at 396 consultations per year the service cost the same as providing a travelling psychiatrist (C$610 per consultation); with more consultations, telepsychiatry was cheaper. Information gathered during the evaluation suggested that the use of videoconferencing for psychiatric consultations was a viable option for an integrated, community-based mental health service.     

Australian GPs are satisfied with their job: even more so in rural areas

BACKGROUND: Australia has seen a constriction of the scope of practice and of professional prerogatives for GPs in the 1990s, which is said to have led to lower job satisfaction, particularly for rural GPs. OBJECTIVE: The aim of this study was to determine levels of job satisfaction and mental health in a rural and an urban sample of GPs, and to correlate population and practice characteristics with lower job satisfaction and morale. METHODS: A postal survey of GP members of two urban and four rural Divisions of General Practice in New South Wales was carried out using the Wall-Cook-Warr scale and the 12-item General Health Questionnaire (GHQ-12). The overall response rate was 74%. RESULTS: Both urban and rural Australian GPs were generally satisfied with their jobs; however, rural GPs had significantly higher job satisfaction scores. The highest levels of satisfaction were recorded for factors denoting autonomy. The lowest ranked factors were hours of work, income and government policy in general practice. GPs without psychological disturbance were significantly more satisfied with their work than those who were disturbed. Lower job satisfaction was significantly associated with urban GPs, GPs who worked full-time and those who used a language other than English during consultations. Poor mental health and working in an urban area were predictive of lower job satisfaction in men, and bulk-billing all patients (i.e. not charging patients a co-payment, but making a consolidated claim to the government funder Medicare) and working full-time were predictive of lower job satisfaction in women. CONCLUSIONS: Both urban and rural GPs derive a large measure of satisfaction from their job. In particular, rural GPs are satisfied, especially so with their autonomy. Poor mental health was the strongest predictor of lower job satisfaction. The high percentage of GPs with psychological disturbances raises the problem of their access to appropriate mental health services, in particular in rural areas.     

The practice guideline 'Consultation psychiatry' of the Dutch Psychiatric Association for psychiatric consultations in primary care and the hospital

Psychiatric consultation in primary care as well as in the hospital is both effective and cost-effective if certain procedures are followed. With the professional guideline 'Consultation psychiatry', the Dutch Psychiatric Association aims at setting a standard for psychiatric consultations in non-psychiatric settings. In general practice, the psychiatric consultation is preferably embedded in 'collaborative care', an integrated care model including the general practitioner and a case manager (usually a nurse), with the consultant psychiatrist being regularly available for clearly defined indications. The psychiatrist should see the patient himself or herself, establish a diagnosis and treatment plan, and provide the general practitioner and the patient with a so-called 'consultation letter', which is then discussed with both. In a general hospital, systematic screening of patients at risk of psychiatric comorbidity can be organised. Early detection of complex patients can further improve the effectiveness of psychiatric consultation. Follow-up contacts and investing in liaison contacts improve adherence to the advice provided.     

Substance misuse and psychiatric illness: prospective observational study using the general practice research database

OBJECTIVES: To quantify the relation between substance misuse and psychiatric illness in the UK general practice population in terms of (a) the relative risk of developing one condition given prior exposure to the other and (b) the proportion of cases of one condition attributable to exposure to the other. DESIGN: Population based prospective observational study using the general practice research database (GPRD) between 1993 and 1998. The 230 GP practices represent 3.1% of the population. SETTING: England and Wales. PARTICIPANTS: 1.4 million registered patients of whom 3969 had both substance misuse and psychiatric diagnoses between 1993 and 1998. MAIN OUTCOME MEASURES: Relative risk (RR) for subsequent psychiatric illness among participants exposed to substance misuse and RR for subsequent substance misuse among participants exposed to psychiatric illness. Population attributable risk (PAR) of psychiatric illness attributable to substance misuse and of substance misuse attributable to psychiatric illness. RESULTS: The baseline prevalence of psychiatric illness over the study period was 15% and 0.3% for substance abuse. RR for psychiatric illness for substance misusers compared with non-substance misusers was 1.54 (95% CI 1.47 to 1.62). RR for substance misuse among psychiatric compared with non-psychiatric cases was 2.09 (95% CI 1.99 to 2.22). PAR for psychiatric illness attributable to substance misuse was 0.2%. PAR for substance misuse attributable to psychiatric illness was 14.2%. DISCUSSION: Only a comparatively small proportion of psychiatric illness seems possibly attributable to substance use whereas a more substantial proportion of substance use seems possibly attributable to psychiatric illness. This study does not support the hypotheses that comorbidity between substance misuse and psychiatric illness is primarily the result of substance misuse or that increasing comorbidity is largely attributable to increasing substance misuse.     

Measuring patient satisfaction: a test of construct validity.

OBJECTIVE--To establish the validity of two patient satisfaction questionnaires (surgery satisfaction questionnaire (SSQ) and consultation satisfaction questionnaire (CSQ)) developed for use in general practice. DESIGN--Prospective study of performance of SSQ and CSQ in patients selected for their predicted levels of satisfaction. SETTING--Avon Family Health Services Authority (FHSA); general practices in Bristol (practice A) and in Cheltenham (practice B). PATIENTS--400 patients selected by Avon FHSA who had changed practices but not their home address and whose original practice had not changed its services (group 1); 869 randomly selected patients (221 from practice A, 648 from practice B) (group 2). MAIN MEASURES--Median difference in satisfaction scores for each questionnaire between groups 1 and 2 and between subgroups of group 2 patients according to assessed level in continuity of care (< 50%, > or = 50%) in the past 12 consultations. RESULTS--272 (68.0%) patients in group 1 completed the SSQ and CSQ. 711 (81.2%) patients in group 2 (178/221 (80.5%) in practice A, 533/648(82.3%) in practice B) completed the SSQ and 374(88/106(83.0%), 286/335(85.4%)) completed the CSQ. Both questionnaires classified patients in groups 1 and 2 according to the construct of satisfaction; thus the difference in median scores for every component of satisfaction in each questionnaire was significant and occurred in the direction predicted by the construct. Each questionnaire also discriminated between patients grouped according to their assessed level of continuity of care. CONCLUSION--SSQ and CSQ are valid measures of satisfaction for these types of patients. IMPLICATIONS--Valid measures of patient satisfaction can be developed; untested instruments should no longer be used.     

Patient reactions to doctors' computer use in general practice consultations

This paper describes an experimental field study of patient reactions to computer use by doctors during general practice consultations. The computer system offered facilities for the review of medical histories and the entry of individual encounter notes. Questionnaire assessments of patient reactions were obtained from 127 patients who had just consulted a doctor who was using the computer and from 216 control patients for whom conventional procedures had been retained. Contrary to many doctors' concerns no overall negative effects were recorded for patient reactions. There were no differences between the experimental and control conditions with respect to patients' perceptions of the doctors' attentiveness and rapport, patients' satisfaction with information received, their confidence in the treatment received, their expected compliance or post-consultation stress. A relation was however apparent between post-consultation stress and attitudes to the idea of doctors using computers in the consulting room, in which unfavourable attitudes were associated with reports of higher stress, and conversely. The results suggest that patient reactions to the consultation are more affected by which doctor they see than by whether or not the doctor is using a computer. However, the findings relate to only a short period of computer use in an experimental context and the effects of more established computer use remain a matter for further enquiry.     

Illness behaviour and patient satisfaction as correlates of self-referral in Japan

BACKGROUND: Patients who frequently change physicians without letters of referral are common, and this has become a source of concern among primary care doctors in Japan. Previous studies have shown a correlation between psychiatric disorders and patient dissatisfaction and the utilization of medical resources. Abnormal illness behaviours such as hypochondria and inappropriate treatment seeking have been associated with various psychiatric disorders. The relationship between illness behaviour and self-referral in Japan has yet to be fully explored. OBJECTIVES: Our aim was to describe the characteristic illness behaviour and satisfaction level of self-referred patients in the general medicine clinic of Saga Medical School Hospital. METHODS: Using the Japanese version of the Illness Behaviour Questionnaire (J-IBQ), we examined the illness behaviour of 277 self-referred patients visiting the clinic. Patient satisfaction with previous medical care was examined with the use of our original Patient Satisfaction Questionnaire. The results were compared with those for physician-referred patients. RESULTS: Self-referred patients differed significantly from original-visit patients on the GH (general hypochondriasis), DC (disease conviction), AD (affect disturbance) and I (irritability) scales and from physician-referred patients on the GH and DC scales. In comparison with physician-referred patients, self-referred patients showed significant dissatisfaction with their most recent medical visit elsewhere. Dissatisfaction toward the medical staff, especially the doctors, was stronger than that toward the medical environment, waiting time or the on-site medical equipment. CONCLUSIONS: It is important to give patients appropriate overall support, not only physical but also emotional, when they first visit a general physician for medical advice. The J-IBQ may be a useful instrument for primary identification of self-referral patients with probable somatization syndromes. Open doctor-doctor and patient-doctor communication is necessary to increase patient satisfaction, which may be helpful to minimize the self-referral phenomenon in Japan.     

The value of case studies

Background: Studies describing GP consultation have identified duration of consultation as an important marker of patient satisfaction. Duration of consultation differs between countries. Objective: The aim of this study was to measure the duration of consultations and the different segments of the consultation in a representative sample of GPs in the Nantes district (France).

Material and methods: 150 GPs in the Nantes district were randomly selected from the telephone directory. A letter of explanation was sent, followed up by a telephone call asking the GPs to receive an observer into their surgery. The observer timed consultations and the different segments of the consultation. Results: 30 out of 150 GPs contacted agreed to participate. 329 consultations were observed. Average duration of consultation was 14 min and 24 s; it was 15 min in non-computerised practices and 12 min and 50 s in computerised practices. Consultations for psychological problems or with many reasons for consulting took longer. Doctors usually talked more than patients, except during long consultations. Patients were not examined in only 2% of consultations. Trainers in general practice had longer consultations. Discussion: Many GPs refused to receive the observer; the ratio of trainers within the group of respondents (40%) was higher than in the general GP population (7–10%). As in other studies, female GPs were overre-presented as active participants. In our sample, the average duration of consultation was longer than in other studies. The finding regarding the duration of consultation in computerised practices may need validation in other studies. EurJ Gen Pract 2000;6:88–92.     

Patient Self-Reported Health,Clinical Quality,and Patient Satisfaction in English Primary Care: Practice-Level Longitudinal Observational Study

ObjectivesTo examine the association of self-reported health of patients in general practices, as measured by the EQ-5D-5L, with practice clinical quality and patient-reported satisfaction with accessibility and consultations.MethodsWe used data from the General Practitioner (GP) Patient Survey to construct a practice-level EQ-5D-5L index as the health outcome. Key explanatories were patient-reported measures of satisfaction with access and consultations (also derived from the GP Patient Survey) and clinical quality measured by the achievement of clinical quality indicators reported in the Quality and Outcomes Framework. We estimated practice-level linear panel data models with random and fixed practice effects and practice and patient covariates using 2012/13 to 2016/17 data on more than 7500 English general practices.ResultsBivariate correlations of the EQ-5D-5L index with quality measures were 0.048 for clinical quality, 0.071 for satisfaction with access, and 0.107 for satisfaction with GP consultations (all with P<.001). In both fixed effects regressions, which allow for unobserved time invariant practice characteristics, and random effects regressions which do not, the EQ-5D-5L index was positively associated with 1-year lags of patient satisfaction with access and GP consultations. Patient-reported health was positively associated with clinical quality in the fixed effects regressions. The implied effects were small in all cases.ConclusionPractice-level EQ-5D-5L is positively associated with clinical quality and with 1-year lags of patient-reported satisfaction with access and GP consultations.     

Patient satisfaction with family physicians and general internists: is there a difference?

Although general internists and family physicians see similar types of patients, they have been found to have different styles of practice. It is not known whether these differences in practice style are associated with differences in outcomes of care such as patient satisfaction. This study examined whether patients of family physicians and general internists have different perceptions of the care they receive. National samples of recently trained family physicians and general internists were asked to complete questionnaires about their practices and to record information on all patient encounters during a three-day period. Three patients were randomly sampled from among those seen by each physician during the study period and were sent questionnaires that included questions about their satisfaction with the medical care they were receiving from the physician. Two hundred thirteen adult patients who saw 124 family physicians and 218 adult patients who saw 98 general internists participated in this study. Patients of general internists and of family physicians reported similar levels of satisfaction on all four dimensions measured (access, humaneness, quality, and general satisfaction) even after controlling for the effects of a variety of patient, practice, physician, and encounter characteristics. It is concluded that the fundamental differences in practice style that have been reported between family physicians and general internists do not seem to be associated with differences in patient satisfaction.     

Psychiatric training for family doctors: what do GP registrars want and can a brief course provide this?

CONTEXT: About 40% of British General Practitioners (GPs) train formally in a psychiatric post as part of their general practice training, but such training may not fully meet the needs of future GPs. A specific course in psychiatry for family doctors has run in Manchester for more than a decade. METHOD: Semi-structured interviews conducted with GP registrars before attending the Manchester course in psychiatry with questionnaire follow-up afterwards to ascertain (a) the training 'wants' of GP registrars and (b) whether the course was providing them. RESULTS: GP registrars most frequently wanted training in communication skills, how to access the resources that are available to GPs, the detection of psychiatric illness, drug treatment and the management of aggression. The course was successful in satisfying the first three but failed in the last two. There was trend for those who attended Manchester Medical School, which scored significantly higher on number of topics covered at undergraduate level, to perceive a greater need for training than those who attended other medical schools. However, there was no evidence to link self-perception of greater need with having already worked in general practice during postgraduate training. CONCLUSIONS: More attention needs to be paid to how to address the specific mental health skills training requirements of GP registrars both within the attachment in psychiatry and during the practice year. Preliminary research is required to devise teaching packages before they are entirely satisfactory for GP education.     

GPs' attitudes to minor ailments.

BACKGROUND: It is generally considered that a significant proportion of 'inappropriate' demand for GP services is generated by consultations for minor ailments. How GPs manage minor ailments is likely to affect how patients perceive and handle similar illnesses in the future. Whilst this potentially has significant implications for general practice workload, research investigating GP' attitudes towards minor ailments and their management is sparse. OBJECTIVE: Our aim was to describe GP' experiences and perceptions of minor ailment consultations and their attitudes towards minor ailment management. METHODS: A questionnaire survey was conducted in 1999, derived from a series of 20 qualitative interviews with practising GPs. The survey was sent to one GP randomly selected from each practice (n = 759) in eight English health authorities. Attitudinal statements were analysed using factor analysis. RESULTS: Four hundred and fourteen GPs (54.5%) completed and returned the questionnaire. Respondents were consulted regularly about minor illness or symptoms, with almost all (95.6%) having experienced a minor ailment consultation in the previous week. Factor analysis suggested four issues to be of importance in determining GP' attitudes to minor ailment management. These were attitudes towards pharmacists, attitudes towards patient empowerment, frustration with minor ailment consultations and attitudes towards caution/risk. CONCLUSION: Although GPs are clearly frustrated by the level of minor ailment consultations, this study suggests that there may be complex factors which influence their attitudes. For the optimal management of minor ailments, inter-professional relationships potentially are of great importance. With increasing patient demand, it is essential that finite health care resources are accessible, appropriate and used in an optimal way.     

The 'Medical Interview Satisfaction Scale' (MISS-21) adapted for British general practice

BACKGROUND: The 29-item 'Medical Interview Satisfaction Scale' (MISS-29) was developed in the USA to assess patient satisfaction with individual doctor-patient consultations. It has been used in studies from British general practice. However, there is limited evidence for its psychometric properties in this population. OBJECTIVES: The present study was designed to examine the validity, reliability and applicability of the MISS-29 in British general practice populations. METHODS: The study was divided into two phases. The first investigated the properties of the MISS-29 in a UK general practice population and resulted in a modified MISS (MISS-21). The second investigated the properties of the MISS-21 in a wider UK general practice population. In phase 1, 150 patients over 16 years were recruited sequentially from patients attending a large group practice in suburban north London. Patients completed a questionnaire which collected demographic data and the MISS-29. In phase 2, 159 patients with a new problem were recruited from patients over 16 years consulting 18 GPs in north London, Essex and Suffolk. Patients completed a questionnaire while waiting to see the doctor; this collected demographic data and included six separate items, designed by the author, intended to measure patient satisfaction with previous consultations with the doctor. The patients completed the MISS-21 when they left the doctor's consulting room. RESULTS: The response rates for the phase 1 and phase 2 studies were 76.9 and 72.6%, respectively. Factor analysis, using principal component analysis with a varimax rotation, of the data collected in phase 1 resulted in a 21-item scale with the same four subscales as the original MISS-29. Correlations between subscales range from 0.46 to 0.65. Values of Cronbach's alpha between 0.67 and 0.92 suggest that the subscales are internally consistent under the conditions of the study. In phase 2, 92.1% completed all the items in the MISS-21 and there were no significant relationships between patients' demographic variables and the proportion of completed MISS-21 questionnaires, nor were there any differences in the proportion of completed MISS-21 questionnaires between type of practice or between practices serving different geographic populations, suggesting that the items were acceptable to patients. There were highly significant positive correlations (0.21-0.63) between scores on the MISS-21 and all aspects of satisfaction with previous consultations, providing supportive evidence for the construct validity of the MISS-21. CONCLUSION: This study has demonstrated that the use in British general practice of the 29-item MISS developed in the USA should be treated with caution. However, a new 21-item version with the same four subscales as the 29-item MISS was developed which has satisfactory internal reliability. The correlations between subscales suggest that they represent fairly discrete but overlapping aspects of satisfaction. Evidence is produced suggesting that patients have less difficulty completing the MISS-21 and that it is applicable for assessing satisfaction with the consultation in different practice types and populations in the UK. Limited data supporting the construct validity of the MISS-21 are presented. While this study does not provide a full assessment of the MISS-21, we believe it provides evidence for its psychometric properties, which suggests that it is a valid and reliable instrument for the assessment of patient satisfaction with individual consultations in British general practice.
